This involves : * saving vms without shutting down (Restoring them can be done with a halt). Is live snapshot enough for this? Is lvm or san snapshot recommended? * saving the postgres database (or only some of main tables). Can we do it without stopping engine and the risk of a data corruption? Is there a howto?

Hi all,
I 'd like to receive any usefull advices from the community about good practice of backing up ovirt with the restraint of zero down time. This involves :
* saving vms without shutting down (Restoring them can be done with a halt). Is live snapshot enough for this? Is lvm or san snapshot recommended?
See http://www.ovirt.org/Features/Backup_API
* saving the postgres database (or only some of main tables). Can we do it without stopping engine and the risk of a data corruption? Is there a howto?
For 3.3 you have share/ovirt-engine/bin/engine-backup.sh for usage please run it with --help You may do it without stopping the engine
Thank you for your help. -- Nathanaël Blanchet

using storage side snapshot could be interesting as well. ayal - thoughts?

live snapshot gives you crash consistent points in time to return to, however, if you want a 'backup' which is stored externally and can then be restored in a different configuration etc then you'd need to utilize the backup API (live snapshot + attach the snap to a virtual appliance and then back it up). live snapshots also integrate with the qemu guest agent so if you've deployed this then you can get better consistency (file systems would be quiesced on linux guests and on windows guests this should cause VSS to quiesce your apps as well). If your storage supports snapshots and your VMs contain a single disk (direct lun) then you can snapshot the lun on the storage side and again get crash consistency. If you could get this to work for you then performance wise this is probably the best option. If your backup solution is integrated with your storage then even better.
* saving the postgres database (or only some of main tables). Can we do it without stopping engine and the risk of a data corruption? Is there a howto?
